Theme Feedback for RP Forum

Hello. Looking around it seems a number of people are going for more unique layouts compared to the standard forum look. However, I am prefer a minimalist style so I struggle to add or change the layout.

I based the theme off of one of the characters form the anime.
Tips and suggestions would be appreciated. Especially ideas on where to move elements or elements to add to make it feel different and less standard. But I hope to also keep a simple and easy to follow layout.
(If you ask me some of these newer unique layouts are too disorienting and hard to follow)
But I would like to make things more interesting at the same time.
